NULL became the default value for object,
so passing NULL to object now has the same
result as not passing any value.

Example #1 Using get_class()
<?php
class foo {
function name()
{
echo "My name is " , get_class($this) , "\n";
}
}
// create an object
$bar = new foo();
// external call
echo "Its name is " , get_class($bar) , "\n";
// internal call
$bar->name();
?>
The above example will output:
Its name is foo My name is foo
Example #2 Using get_class() in superclass
<?php
abstract class bar {
public function __construct()
{
var_dump(get_class($this));
var_dump(get_class());
}
}
class foo extends bar {
}
new foo;
?>
The above example will output:
string(3) "foo" string(3) "bar"
